ICD-10 Code D25.9 – Leiomyoma of uterus, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D25.9 – Leiomyoma of uterus, unspecified
What it is
D25.9 identifies a benign smooth muscle tumor of the uterus when the record does not specify the exact location. Use this code when documentation says uterine leiomyoma, fibroid, or myoma without further detail.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include an enlarged or irregular uterus, pelvic pressure, abnormal uterine bleeding, or bulk-related symptoms, but the diagnosis should be supported by imaging or exam notes.
When to use this code
Use D25.9 when the provider documents a uterine fibroid or leiomyoma and does not identify submucous, intramural, or subserosal type. It also fits when the chart only states “fibroid uterus” or “uterine myoma” without further specificity. If laterality or site is clarified, code the more specific option instead.
Do not use for
Do not use D25.9 if the record specifies a different leiomyoma subtype, because a more exact code is available. Do not assign it for malignant uterine neoplasms or for nonspecific pelvic masses without documentation of leiomyoma.
Coding tip
Check the pathology, imaging, or provider assessment for the exact uterine leiomyoma type before defaulting to the unspecified code.
